The Teeth of the Tiger follows Jack Ryan Jr., son of the former President, as he secretly joins "The Campus"—an off-the-books counterterrorist organization operating beyond government oversight. When Islamic extremists slip across the U.S.-Mexican border with plans to attack American shopping malls, the Campus's covert operatives spring into action. Alongside his cousins Brian and Dominic Caruso, Jack enters a deadly world of espionage, targeted assassinations, and looming homeland threats. As the body count rises and conventional intelligence proves useless, these young operatives must hunt down a ruthless enemy determined to bring terror to American soil.
